What caused CHTR's revenue cost decline in Q1 2024?

Charter Communications (CHTR) experienced a decline in revenue and cost of revenue in Q1 2024, primarily due to the following factors:

1. **Decline in Internet Subscribers**: Charter lost 61,000 internet subscribers in the quarter, which is a significant factor contributing to the revenue decline. Analysts had expected the company to add 6,000 internet customers, but the actual outcome was a loss.
2. **Cord Cutting Acceleration**: The trend of customers cutting the cord and switching to streaming services continued to impact Charter. The company lost 257,000 video customers, which is worse than the expected decline of 194,000.
3. **Competitive Pressure**: Charter faces intense competition from other telecommunication and cable providers offering wireless and fiber services. This competition has led to a challenging environment for Charter's traditional cable business.

In summary, the decline in revenue and cost of revenue in Q1 2024 is primarily due to the loss of internet subscribers, cord cutting acceleration, and competitive pressure.
